Hello!

I have this problem that i cant quite figure out.As the title says im hearing everything with a slight higher pitch and its been happening for months, and when it does happen, it usually stays for a day.PS. This is usually accompanied with a slight headache.
It started a few months back.One day i wake up and hear everything in a higher pitch, it stayed like that for the entire day, but it only happened once or twice a month and thats it, but im getting concered and id like to know what this is.
Prior to this, last night i played a gig with a band,drank alcohol,stayed up till 4 AM, slept only 5 to 6 hours.

This might also help.I play in 3 Bands and im constantly in band practices etc. with loud noises for hours.

Please Help and thank you for your time.
